Abstract: A client platform supports digital rights management. The client platform comprises a digital rights management (DRM) engine which, when executed, enables the client platform to monitor download operations performed by the client platform and to obtain a shadow image for a digital content item from a DRM blockchain, in response to an operation to download the digital content item from a remote source. The shadow image comprises a hash of the digital content item and copyright policy settings to indicate security constraints for the digital content item. The client platform may automatically determine whether the copyright policy settings for the digital content item allow modification of the digital content item. A user may be allowed to create a modified version of the digital content item only if the copyright policy settings allow modification of the digital content item. Other embodiments are described and claimed.
